           Summary: Cannot enable access to off-chip flash on at91sam7se32
           Product: eCos
           Version: 2.0
          Platform: at91sam7sek_256 (AT91SAM7S-EK board with AT91SAM7S256)

Exported ecc file

We are currently developing using eCos V2 on the Atmel at91sam7se32.

The base configuration used was V2.0 for the at91sam7s256, using the Posix
template as a starting point. We have tried to add in JFFS2 support on off-chip
flash, but are having difficulty accessing the off-chip flash fitted to our
board, in that eCos seems locked to on-chip flash only.

To try and enable this we have merged in files from eCos V3, in the appropriate
dev, fs, io, hal. I have attached the exporeted ecc file that we are using. It
does not populate the DEVTAB with the flash2 or jffs2-2, even though the
options are selected and no conflicts are highlighted.

It looks as though the value for CYGHWR_IO_FLASH_DEVICE is, currently, not set
properly, which is why it fails. How can this be changed and what new flash
files do we need to create/modify to interface to our off-chip flash memory and
where should they be placed?
